New Records for GASTROPODA Class of Species Found in the Rocky Intertidal Zone of the Marine Priority Region 32, Guerrero, Mexico

Abstract

The GASTROPODA class, one of the best known marine environments, is formed by a large number of species and the shape of their shell structure varies greatly. These mollusks are distributed from the intertidal zone all the way to the abyssal zone, and there are also swimming and floating species. This research was conducted at seven sites, located in the Marina Priority Region 32 (MPR 32), located in the State of Guerrero, Mexico. The aim of this report is to document the scope of the geographic distribution of the 34 species of GASTROPODA class. 11,263 total specimens were analyzed. 108 species were identified, of which four species are new records for Mexico, 15 for the Transitional Mexican Pacific, 11 for the State of Guerrero and four for the MPR 32. Here we report a significant number of new records of species of class GASTROPODA found on the rocky intertidal zone of the MPR 32. The reporting of these new records, demonstrates the need to focus research efforts on the study of marine diversity, since knowledge in this respect is quite incomplete, especially regarding marine mollusks, a fact that has been reported by the National Commission for the Management and Use of Biodiversity.
